There was a problem such as being crowded or damaged.
본 발명은 상기와 같은 사정을 고려하여 안출한 것으로서, 본 발명의 목적은 자동차의 범퍼에 노면 검출센서를 부착하여 이 센서에 의해서 노면 불량상태를 검츨하면 트로틀 밸브를 제어하고 브레이크를 작동시켜서 자동차 속도를 일정속도 이하로 줄일 수 있게 하므로 노면 불량으로 인한 사고의 위험을 방지할 수 있게 한 것이다.The present invention has been made in view of the above circumstances, and an object of the present invention is to attach a road detection sensor to a bumper of a vehicle and detect a road fault condition by this sensor to control the throttle valve and operate a brake to operate a vehicle speed. It is possible to reduce the speed below a certain speed to prevent the risk of accidents due to poor road.

이와 같은 본 발명을 바람직한 실시예에 따른 첨부도면에 의거하여 상세히 설명하기로 한다.This invention will be described in detail based on the accompanying drawings in accordance with a preferred embodiment.
제1도는 본 발명의 실시예에 따른 자동차의 노면 검출제어 장치의 회로도를 나타낸 것이다.1 is a circuit diagram of a road detection control apparatus for a vehicle according to an embodiment of the present invention.
상기 도면에 의하면, 발광센서(11)를 통해서 노면에 발광하는 신호를 감지하는 수광센서(12)로 노면의 상태를 감지하는 노면감지부(10)를 콘트롤부(30)에 연결하고, 자동차의 속도를 감지하는 속도감지부(20)의 신호를 콘트롤부(30)에 입력시킨다.According to the figure, the road surface detection unit 10 for detecting the state of the road surface to the control unit 30 by the light receiving sensor 12 for detecting a signal that emits light on the road surface through the light emission sensor 11, The signal of the speed detecting unit 20 for detecting the speed is input to the control unit 30.
상기 콘트롤부(30)에서 노면 감지부(10)와 속도감지부(20)의 신호를 입력으로하여 노면상태가 불량이고 속도가 일정속도 이상일 경우에 워밍램프를 점등시키도록 하는 워밍램프점등회로(40)와, 엔진의 연료공급을 조절하여 자동차 속도를 제어하는 트로트밸브를 조절하도록 하는 트로트밸브 제어부(50)와, 브레이크를 제어하여 자동차 속도를 일정속도 이하로 유지시키도록 하는 브레이크 제어부(60)를 연결한다.Warming lamp lighting circuit 40 to turn on the warming lamp when the road surface state is bad and the speed is above a certain speed by inputting the signals of the road surface sensing unit 10 and the speed detecting unit 20 from the control unit 30. ), A trot valve control unit 50 for adjusting the fuel supply of the engine to control the vehicle speed, and a brake control unit 60 for controlling the brake to maintain the vehicle speed below a certain speed. Connect.
제2도는 본발명의 실시예에 따른 노면 감지부에 따른 센서를 부착시킨 상태에서 노면을 감지하는 상태를 보인 도면으로서, 발광센서(11)에 의해서 발광되는 빛을 수광센서(12)로서 수광하는 시간을 거리로 연산하여 노면의 불량한 상태를 감지하도록 한 것이다.2 is a view showing a state of detecting a road surface in a state where a sensor according to a road surface detection unit according to an embodiment of the present invention is attached, and receives light emitted by the light emitting sensor 11 as a light receiving sensor 12. By calculating the time as a distance to detect the bad state of the road surface.
이와같은 본 발명의 작용효과를 상기도면에 의거하여 설명하기로 한다.Such effects of the present invention will be described based on the above drawings.
제2도와 같이 자동차의 앞 범퍼측에 부착한 노면감지부(10)의 발광센서(11)에서 신호를 수광센서(12)에서 수광하는데, 노면상태가 양호한 상태에서는 발광센서(11)가 발광한 신호와 수광센서(12)에 수광한 신호가 거의 같게 되지만 둔턱이진 경우에는 수광신호의 검출시간이 매우 짧게되고, 웅덩이와 같이 홈이 파인곳에서는 수광신호의 검출시간이 길게 된다.As shown in FIG. 2, the light receiving sensor 11 of the road surface sensing unit 10 attached to the front bumper side of the vehicle receives a signal from the light receiving sensor 12. When the road surface state is good, the light emitting sensor 11 emits light. The signal received by the light receiving sensor 12 is almost the same, but in the case of a barrier, the detection time of the light receiving signal is very short, and the detection time of the light receiving signal is long in the grooved area such as a puddle.
그리고 상기에서 수광신호의 검출시간은 자동차 속도에 따라서 변할 수 있으므로 자동차 속도감지부(20)에서 감지한 신호와 비례하여 연산하여야만 정확한 수광신호에 의한 불량노면을 감지할 수 있게 된다.In addition, since the detection time of the received light signal may vary depending on the speed of the vehicle, it is necessary to calculate the proportion of the received light signal in proportion to the signal detected by the speed sensor 20 so as to detect a bad road surface due to the correct received signal.
상기와 같이 노면 감지부(10)에 의해서 불량한 노면을 감지하게 되면, 워밍램프 점등회로(40)에 의해서 워밍램프가 점등되므로 운전자는 불량한 노면 상태를 확인하고 이에 따른 대처를 하게 되고 자동차 속도에 따라서 트로트벨브(50)에 의한 엔진의 연료를 조절하여 트로트밸브를 조절하여 엔진의 구동력을 줄여서 자동차 속도를 줄이게 함과 동시에 브레이크 제어부(60)에 의해서 브레이크를 작동시켜서 자동차 속도를 일정속도 이하로 줄여주므로서 노면 불량으로 인한 사고의 염려를 줄일 수 있게 한다.As described above, when the road surface detecting unit 10 detects a bad road surface, the warm lamp is turned on by the warm lamp lighting circuit 40, so that the driver checks the bad road condition and responds accordingly. By adjusting the fuel of the engine by the trot valve 50 to control the trot valve to reduce the driving speed of the engine to reduce the vehicle speed and at the same time by operating the brakes by the brake control unit 60 reduces the vehicle speed below a certain speed This can reduce the risk of accidents caused by poor roads.
이와 같이 본 발명은 자동차 속도에 따른 노면 감지에 의해서 워밍램프와 엔진의 트로트밸브 및 브레이크를 작동시켜서 자동차 속도를 자동으로 줄여줄 수 있게 하므로 노면불량으로 인한 사고의 위험을 미연에 방지할 수 있게 한 유용한 것이다.As described above, the present invention enables to automatically reduce the vehicle speed by operating the warming lamp and the engine's trot valve and the brake by detecting the road surface according to the vehicle speed, thereby preventing the risk of an accident due to the road surface defect. It is useful.
